How predictive are laboratory experiments for assessing the effects of chitin synthesis inhibitors (CSI) on field colonies of terrnites? - A comparison of laboratory and field data from Australian mound-building species of termit
1996 - IRG/WP 96-10143
A singular advantage of using mound building species of termite is their directly accessible nest. This allows evaluation of control methods by accurate assessment of the effects at the colony level. The mound building species Coptotermes acinaciformis (Froggatt) and Nasutitermes exitiosus (Hill) were used to test the CSI, hexaflumuron, in laboratory and field trials. Laboratory results showed tha...

Estimation of the population of a sound colony of Coptotermes lacteus (Froggatt)
1988 - IRG/WP 1353
Selecting an area with a high termite hazard is deemed essential in locating field sites in order to screen potential termiticides and wood preservatives. Yet, quantifying termite populations in such sites remains imprecise. There are major problems associated with estimating populations of termites in mound colonies (either free-standing or in trees), and these are briefly discussed. In this pape...

Intraspecific variability in feeding capacity of Coptotermes acinaciformis (Froggatt) (Isoptera: Rhinotermitidae)
1983 - IRG/WP 1175
This paper describes laboratory studies to evaluate the comparative feeding capacity within and between five mound colonies of Coptotermes acinaciformis (Froggatt). Matched specimens of mountain ash, pine and coachwood were exposed to five replicate 10 g groups of termites from each colony source. After an initial 8-week exposure period, all groups were assessed for vitality and continued feeding ...

Comparison of various types of bait containers designed to aggregate large numbers of foraging subterranean termites from natural populations in below-ground mound colonies
1995 - IRG/WP 95-10116
At Walpeup in the semi-arid mallee country of north-west Victoria (350 km from Melbourne), there are several indigenous subterranean termite species, none of which build above-ground mound colonies but build their colonies below-ground and/or in trees. This paper describes a baiting experiment in which three types of bait containers were compared in their ability to aggregate large numbers of fora...

The gaseous environment of Coptotermes lacteus mound colonies before and after mirex treatment
1989 - IRG/WP 1396
While monitoring the halocarbon and hydrocarbon emissions from a dry sclerophyll eucalypt forest in central Gippsland, similar emissions were collected from within several Coptotermes lacteus mound colonies. Samples of the gases (hydrocarbons) from within the mounds were collected before, during and after treatment with mirex-treated wood-decay blocks. All the mirex-treated mounds died within two ...

The “wire-loop slicing technique” for the rapid field collection of large numbers of Coptotermes acinaciformis termites from above-ground mound colonies
2006 - IRG/WP 06-10583
This technique of rapidly slicing through an above-ground C. acinaciformis mound colony with a steel wire-loop attached to a vehicle allows the collection of large numbers of termites. The sliced mound topples onto a tarpaulin arranged on the ground, the outer wall layers break away in large segments, and the carton materials incorporating the termites are readily collected and transferred to larg...
